BENJAMIN DUDLY PATRICK, OF APPLETON CITY, MISSOURI.

, BUMPER FOR DOORS.

BPECIEICATION forming part of Letters Patent No. 335,616, dated February 9,1886.

Application filed July 10, 1885. Serial No.17l,163. (No model.)

To aZZ whom it may concern:

Be it known that I, BENJAMIN D. PATRICK, a citizen of the United States, residing at Appleton City, in the county of St. Clair and State of Missouri, have invented certain new and useful Improvements in Bumpers for Doors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

In the accompanying drawings, illustrating my invention, Figure 1 is a perspective view of my improved bumper applied to the baseboard of a room in a position ready to receive the bumper-catch, which in this figure is shown in a position ready for coming in contact with the front or forward end of the bumper, and which bumper-catch is supposed to be attached to a door which has been swung open in a direction toward the baseboard to which the bumper is applied. Fig. 2 is a plan view of Fig. 1, the only change being in the style of the thumb-button employed to fasten the bumper in position. Fig. 3 is a plan view showing the bumper attached to the base-board in a reversed position from that shown in Fig. 2, thereby allowing an angular adjustment to be made in a reversed direction from that signified in dotted lines in Fig. 2. Fig. 4 is a plan view of the bumper having an adjustability either to the right or the left hand, according as it may be applied to the base-board, so as to have its adjusting-nut either on the left-hand side of the bumper, as shown, or on the right-hand side, as in Fig. 3.

My invention consists,first,in a spring-plate for either a bumper, or a combined bumper and holdback, provided with a hinged fastening-plate, and with a slot and clamp, by which the bumper, or bumper and holdback combined, can be adjusted to any desired angle with respect to a door; and, second, in the combination of india-rubber bumpingrollers or equivalent device with the hinged and adj ustable spring-plate.

In Fig. l I have represented my improved bumper A firmly attached to the base-board B of a room by screws passing through metal plates a a a", to which the limbs C C of the bumper are confined by hinges b b, as shown.

of spring metal of suitable width, and with its extreme outer end portion in circular form, as L d d. between which the springmetal plate is made with an open expansive loop, 6, and so extending on rearwardly isv made to connect with the limb C, and be held in clamped contact therewith byaserew-nut, g, upon a screw pintle, g,which,as indicated, is fastened to the terminating portion of the limb C, and passes through a longitudinal slot, h, in the limb C, as shown.

In Figs. 1, 2, and 3,1nmindicate india-rubber friction-rollers,which may turn upon axial pins 1) p,which pass through upper and lower circular metal blocks, r r, secured in proper manner to the circular portions d d of the limb C, a portion of the metal of the limb C being cut away, so as to permit the use of the rollers m m, as shown. In the figures only the upper circular metal blocks,r r,are shown, said upper and lower blocks forming proper upper and lower bearings for the friction-rollers as they move upon their axes p p.

In Fig. 4 I have shown my adjustable bumper with its bumping curved end a covered with a cap, m, of india-rubber, held in place, as shown,by a band of rubber, in, and thus a bumper is formed of the same general character as that shown in the other figures, and

with its bumping end n provided with rubber, as W, to receive and deaden the blow of a door swung against it, the same as would be the action of the rubber rollers m m in Figs. 1, 2, and 3,when used solely for such purpose. In Fig. 1 I have, however, shown an additional feature-to wit, a holdbaek capability of the bumper, and which I will now more par ticularly describe.

As before stated, Fig. 1 shows a bumpercatch supposed to be attached to a door in proper position to haveitself caught and held firmly by the forward end of the bumper A when the door is swung open. To this end the bumper-catch L is made of a single piece of metal, with ends ttfor attachment by screws to a door, and with a round or oval bumping end, 6, as showmwhich in form is such as will readily force its way between the rollers m m, and into theloop e of the bumper A,un.der the swinging impulse'of the door to which it may be applied, and during which act the rollers m m not only serve as bumpers to receive the blow,but as friction-rollers to facilitate the entrance of 6 into the loop 6, the spring action of theloop ebeingsuoh as to allow the entrance of the oval bumping end 6 of the catch L, and clasp and hold it therein when once entered, against any back action of the door to free itself from being held back.

As indicated in Figs. 1, 2, and 4, my improved adjustable bumper may be adjusted to the right hand at any desired angle for use, while in Fig. 3, the attachment to the baseboard B being made so as to bring the clamp on the right hand of the bumper, the adjustment is made to the left, as indicated by dotted lines :0 m, and thus my bumper, by having a capability of being set against the base-board in a reverse position, as shown, can be adapted to the varying conditions of its use, in all of which it is necessary to have its bumping end presented at right angles with the striking-face of the door.

What I claim as my invention is- 25 1. Metal spring-plates C O for a door-bumper, and a combined bumper and holdback pro vided with a hinged fastening-plate, and a slot and clamp, by which the bumper and the bumper and holdback combined can be adjusted to any desired angle with respect to a door, substantially as described.

2. The combination of india-rubber bumping-rollers m m, or their equivalent, with the hinged and adjustable hinged plates 0 0, sub- 5 stantially as described.

3. The combination of the hinged and adj ustable spring-plates provided with an expansible loop, e, and the bumper-catch L, sub stantially as and for the purpose described.

In testimony whereoi'l affix my signature in presence of two witnesses.

BENJAMIN DUDLY PATRICK.
